There’s different levels:

1. Shutdown at UEFI splash
2. Long press power button
3. Unplug PC
4. Turn off PSU
5. Turn off extension cord
6. Turn off room’s breaker
7. Turn off main breaker
8. Cut off the power lines
9. Shutdown the power plant
10. Declare war on any community using electricity
11. Declare war on thunder clouds
12. Destroy everything with electrons (total annihilation of the world)

I have never, not once, had this not just immediately begin updating anyway.
